Fair enough. Go on then, show us your estimate for the cost of renting a fully charged towable battery for 2-3 days. I'm struggling to see it being much cheap

  > I'm struggling to see it being much cheaper than renting an ev for 2-3 days if such a thing were wished into existence. Even if it was the same price, lots of people don't want to rent a car, and many of the reasons they have for that don't apply to renting a battery pack. But I'd be surprised if it wasn't a lot cheaper. If I think about a non-towed battery, it costs 1/5 as much as a car, needs 1/10 as much storage space on shelves, and can be kept in service for hundreds of thousands of miles. Towed units would be harder to store and have a bit more wear but should still be a lot smaller and cheaper than cars. A small trailer that could carry a battery is only a thousand bucks retail. You'd probably want some cooling, in the end maybe it's 1/4 the cost of a car and takes up 1/6 of a parking space? Still sounds like a cheap rental. And as for the price of "fully charged", they can have the same price per kWh as a supercharger and have massive profit margins. So that's an amount you'd have to pay anyway and not a downside to renting.
